Life stages of the Serpiente Rey

Each stage has its own care priorities. Life expectancy: 15-25 años.

Neonate

0-3 months

Small, secure terrarium, 24-30 °C gradient; pinkies every 5-7 days; substrate that holds slight humidity for the first shed.

Juvenile

3-12 months

Increase prey size (fuzzy/hopper mouse) every 7 days; warm spot 28-30 °C; always house alone (snake cannibalism).

Subadult

1-2 years

Hides in the cool and warm zones; adult mouse every 7-10 days; watch for complete sheds and a clean mouth.

Adult

2-25 years

24-29 °C gradient, no mandatory UVB; suitable prey every 10-14 days; in females monitor egg retention after laying.

Care

Terrarium: minimum size depending on species (check species-specific guides). UVB essential for diurnal species.

Temperature: day/night gradient · warm zone vs cool zone for thermoregulation.

Humidity: depending on species (rainforest 70%+ · desert 30-50%).

Feeding: species-specific diet · insectivores, herbivores and carnivores vary radically.

Vet: exotics vet (a regular vet WON'T do). Annual check-up.

Care in detail

🍽️ Nutrition

Carnivore: thawed rodent as thick as the snake every 5-10 days (adults every 1-2 weeks). Always housed alone due to its tendency to eat other snakes.

✂️ Grooming

🎓 Training

Docile and hardy; with short, regular handling it becomes very manageable. Don't hand-feed to avoid bites out of confusion.
